# CFWeb3

CFWeb3 is a Web3 demo application. It uses [Hardhat](https://github.com/nomiclabs/hardhat) and [Solidity](https://soliditylang.org/) to create an [Ethereum](https://ethereum.org/) smart contract. This code is a proof-of-concept showing how to [build Web3 applications with Cloudflare](https://blog.cloudflare.com/get-started-web3/), and should not be used as a production example.

The contract offers 2048 tokens which can be minted via the frontend [Svelte](https://svelte.dev/) application. The entire app runs on the [Rinkeby](https://www.rinkeby.io/) test network.

## Demo

A live version of this demo app can be found at [cf-web3.pages.dev](https://cf-web3.pages.dev/).
